According to Chapter 17, what are the primary obstacles that prevent a person from attaining knowledge and choosing the path of Shreya?

Chapter 17 identifies several significant obstacles to spiritual progress and the attainment of knowledge. The primary hindrance is described as beginningless ignorance or Maya, a false imposition as unreal as a mirage. The text also explicitly warns against desires for seen and unseen enjoyments, hope, and cravings, stating they must be dug out by the roots. Furthermore, Chapter 17 names lust and anger as two powerful tendencies that disrupt the essential spiritual practices of listening, contemplation, and meditation. A restless heart and a mind distracted by the greed of the senses are also cited as reasons why even a knowledgeable person cannot find peace.
